Synchronization delays between Motive and Ni-DAQ

Post by Gary Ohanessian »

Hello,

We have been testing the synchronization between Motive 2.1.1 and two NI-DAQ systems (NI USB-6341 (BNC), NI-DAQmx 21.3).

We are using the reference clock sync setup from Optitrack Wiki using the eSync 2 synchronization device. The Motive MoCap is the master and the NI-DAQ systems are the slaves.

We have found that delays between Motive and NI-DAQ systems range from -0.005 to 0.08s (200Hz Sample Rate) with no apparent patterns.

As this has been reported somewhere else, has anyone found a solution to this problem? Or does anyone know how to resolve this problem?

Thank you for your time,
Gary
